Tie-IxHash (1.21)

There are really occassions when you want the order preserved. Consider the following snippet for XML special character conversion. You can now say:

tie (%escape_symbols, Tie::IxHash,
qq (&) => '&',
qq (\042) => '"',
qq (>) => '>',
qq (<) => '&lt;'
);

Imagine using these key,value pairs in a regex for substitution. Here the order is vital, as the & signs needs to be replaced first, otherwise your routine might clobber over the & symbols you use for the other replacements!

Neat and simple package, that does exactly what it says it will do.

I only use it on rare occasions, but when I need it, it's great. It does exactly what it says: you get a hash that preserves order. Great!

If you need an ordered hash, this is the module for you. Very handy and well documented.
